Ok I see. So you expected exit() to work same as on, say, Linux. So that app just exits back to the shell. According to function documentation is should work like that

Don't know why it asserts, maybe you miss some config? Your best bet to fix it is to put breakpoint at your exit() function, and step through the code. Nuttx is exceptionally well documented in its C files, you will have no problems following it. -- .-----------------.-------------------.----------------------.-----------------. | Michal Lyszczek | Embedded C, Linux | Company Address | .-. opensource | | +48 727 564 419 | Software Engineer | Akacjowa 10a; 55-330 | oo| supporter | | https://bofc.pl `----.--------------: Brzezinka Sredzka PL | /`'\ & | | GPG FF1EBFE7E3A974B1 | Bits of Code | NIP: 813 349 58 78 |(\_;/) programer | `----------------------^--------------^----------------------^-----------------'
